Arch Linux User Repository

@jackoneill I've been running with those options in modprobe.d using the built-in kernel module for a few days now and my system hasn't crashed so far. I'll report back if it does

@senorsnor: Those patches do the same thing as putting „options rtw_pci disable_aspm=1” in a file in /etc/modprobe.d/, but only for those specific machines. („rtw88_pci” for the built-in module, and „rtw_pci” for lwfinger's version.)

Have you tried that option? I tried it and it didn't help. My laptop is HP 250 G7.

Recently some patches were done describing the exact same symptoms some of us face:

Both "disable pci capabilities" based on hardware model: Protempo Ltd L116HTN6SPW and HP Pavilion Laptop 14-ce0xxx respectively. I'm not familiar with C or kernel/driver development so I don't know exactly what this is about, but this solution worries me:

My laptop, which shows the exact same symptoms, is an HP Pavilion Laptop 15-cs0xxx (note the 15-cs, rather than the 14-ce as in the patch).

Before I reply with this to the mailing list, I thought I make an inventory here with the people that run into the same issue. Which hardware are you using?

You can find the info with the command sudo dmidecode | grep -A3 '^System Information'

For me the screen doesn't update either, mouse movements and key presses are not processed anymore. System is completely frozen. Not sure about the fan speed during a system freeze.

When using the kernel drivers, my system feels unstable. Fan speed goes up and down at seemingly random moments. When I tested with rtw88-dkms-git that seemed to have disappeared, unfortunately my system still freezes.

@CodingEagle02: It doesn't look like that here. The screen looks normal, it just doesn't update anymore. The mouse cursor doesn't move. Ctrl+Alt+F1..6 have no effect. The fan may speed up a little after a while. It doesn't go full speed. I didn't try the Sysrq stuff.

What kinds of freezes are you all getting? I've noticed I get a really weird and specific, where my screen suddenly goes black, and my fan starts going at full speed. The kill X server command doesn't work, but REISUB mostly does. I never used to get these. I'm too lazy to post the logs somewhere at the moment, but if people are dealing with the same thing, then I guess it's just a matter of waiting until Linus and Realtek get their shit together.

@jackoneill ok too soon .. system just froze twice with rtw_8821ce

@jackoneill Thanks for that, then indeed I tested with the current kernel driver. Now testing rtw88-dkms-git for a few hours and so far it works great. If the system crashes then i'll report here.

The driver that comes with the kernel is called rtw88_8821ce (and rtw88_{8821c,pci,core}). The driver in the rtw88-dkms-git package is called rtw_8821ce (and rtw_{8821c,pci,core}). The driver from the kernel seems to have higher priority. So the file in /etc/modprobe.d/ needs to contain these lines:

blacklist rtw88_8821ce blacklist 8821ce
